Op b 1/8 is correct..
I hope it helps u

Answer 2

Answer:

no need to do so many things in the above Answer given by Navjot . follow my simple steps below ↓

Step-by-step explanation:

given : tan∅+sec∅ or sec∅+tan∅ = 8

therefore, we know sec²∅-tan²∅=>(sec∅-tan∅)(sec∅+tan∅)=1. [a²-b²=(a+b)(a-b)]

=>8(sec∅-tan∅) = 1

=>sec∅-tan∅ = 1/8

Answer = 1/8

hope it helped .

thanks !
